This invention relates to a universal gang winding apparatus or reel particularly adapted for, but not limited to, the winding of the field coils of motors or other electrical apparatus and it generally aims to simplify and render 'more practical and efficient, a machine of the present character.

It is further sought to provide an apparatus of the foregoing nature which will enable use thereof for the winding of various shapes and sizes of coils through expeditious adjustment of the parts without requiring detachment or removal of parts, such a construction having readily displaceable parts for the release of the coils, and a construction which may utilize novel one-piece jaws.

Another important object is to provide a form wherein a plurality of said jaws are carried by preferably four relatively adjustable plates, on which plates the jaws are mounted for fastening at various angles, certain of the parts optionally having graduations to assist in the accurate positioning of the jaws.

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating operative embodiments by Way of example.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, I! designates a horizontally deposed u shaft which is adapted for rotation in either direction by any suitable means, manual or power, and for instance by means of an electric motor. The outer end of said shaft has parallel grooves i8 therein occupied by portions of spaced apart rails E9 of a support or mount 20, said portions being detachably secured in place as at 2i and the support or mount having slots 22 on opposite sides of said shaft.

Adjustable toward and away from each other along and supported on said mount 20 on opposite sides of the axis of rotation are auxiliary mounts or brackets 23. A pair of plates 24 are carried by each auxiliary mount or bracket 23 so as to move with the auxiliary mounts and also so that the plates of each pair will be adjustable toward and away from each other. Said plates 24 carry jaws 25 about which the wire or other material is wound.

More specifically, each auxiliary mount or 35 bracket 23 is in the shape of an open, rectangular frame providing spaces 26 in which adjusting screw rods 2'! have trunnions or reduced end portions 28 and 29, respectively, journaled in an opening 36 of an end wall 3!, and in an opening 32 provided collectively in a reduced end wall 33 and a cleat screwed thereto at 34.

Said adjusting screw rods 21 have a reduced portion 35 affording a journal midway of their ends, journaled in an opening 36 collectively formed in a block or projection 3'! rigid on the auxiliary bracket and a cleat 38 detachably screwed at 39 to such block 3?. Blocks or projections 3! project rearwardly beyond the auxiliary bracket and are slidably disposed in the slots 22 and are adapted to be rigidly clamped in various adjusted positions by means of nuts 40 engageable against the rails l9 and operable on screw studs ll carried by the blocks. Nuts 40 preferably have cranks 42 to facilitate manual operation.

Screw threads of opposite pitch are provided at 43 and 44 on each adjusting screw rod 21 on opposite sides of its journal portion 35 and engaged on said threads 43 and 44 are non-rotatable nuts 44 and 45 to each of which, one of the plates 24 is fastened as by means of screws 46. Said nuts slide in the spaces 26 and the plates 24 slide on the rails l9.

Said trunnions 29 have pins 41 fastened diametrically thereof and they are adapted for engagement by a slot in one end of a crank or equivalent tool 48 used' in rotating the screw rods 21 when adjusting the position of the plates 24.

Pivotally connected to each plate 24 adjacent the corner nearest the axis of rotation, as by means of a pin or screw 49, is a jaw member 50 which has a bolt extending therefrom through an arcuate slot 52, enabling adjustment and positioning of the jaw at various angles, in which the jaw is rigidly fastened as by means of nuts 53 on the bolts 5|, engageable against the rear surfaces of the plates.

Said jaw members 5!! are preferably made in a single piece, relatively narrow and substantially triangular, with a series of guides, notches or the like 54 in the inclined edges thereof for engagement by the wire or material 55 being coiled, as best shown in Figure 6, the bases of the said guides or grooves preferably being rounded or convex as at 56 so that the coils wound will be correspondingly rounded at the corners as shown at 5? and 58 on the coils A and B of Figures 5 and '7, respectively, which have been wound on the apparatus.

Since the adjustment or positioning of the jaws must be very accurate in many instances, various millimeter or micrometer graduations are provided to facilitate the same, as at 59 on plates 24; at 60 on the auxiliary mounts 23 and at ti on the support or mount 21!. The jaws 50 are pointed at 52 to cooperate with the graduations 59 and the plates have pointers or indicators 63 on the rear thereof coacting with the graduations 6i In operation, as the device as a whole is rotated through rotation of shaft II, the Workman applies the wire or material 55 which coils about the jaws 59 to produce a field coil for a motor, as in Figure 5 when the jaws are adjusted like in Figure 4, or as in Figure '7 when the jaws are adjusted as in Figures 1 and 6. It will be realized that. all parts are in rigidly connected relation as the coil is wound. In order to vary the sizes and shapes of the coils to be wound, the nuts 40 may be loosened and the auxiliary mounts 23 slidably moved manually toward or away from each other, being guided by the blocks 3! and slots 22, following which the nut or nuts 4b are tightened. The plates 24 and jaws, of course, move with saidauxiliary mounts 23. In addition, the plates 24 of each auxiliary mount may be adjusted toward or away from each other through the turning of the proper screw rod 2'! by means of crank 48, the plates remaining in the different positions because of the screw thread engagement between the nuts 44' and 45 and threads 43 and 44. This adjustment through the medium of the screw rods 21 also enables contraction of the plates 24 and jaws to release coils after completion, avoiding the necessity of removing and replacing any of the parts. It will also be realized that the one size of jaw will enable many sizes and shapes of coils to be wound on the same machine, since the jaws may be readily and expeditiously disposed at any desired angle when the nuts 53 are loosened for that purpose. Two of the many adjusted positions of the jaws 50 are shown in Figures 4 and 6.

A modified form of jaw is shown in Figure 13 being designated 10. One face, that is the outer face thereof ll is rounded while such face and the side faces are also inclined or tapered. The grooves or guides are formed by the various ribs 12. The jaws like the preceding form, are substantially triangular and they are used four at a time or one on each plate 24, being either rigidly or adjustably fastened to such plates as desired. With such a jaw used in the apparatus, an oblong coil with rounded ends as at 13 in Figure 14 is produced.

In Figures and 16 another form of apparatus and jaw is disclosed. This form has a mount or support adapted for rotation at 85 to which four plates 8! are fastened in the same manner as the plates 24 in the first form, each of which has a jaw 82 fastened thereon provided with notches 83, the base walls of which are rounded or convex as shown at 8 5. In connection with such jaws, arms 85 are removably clamped to mount 86 as by means of screws 8%. Said arms 85 carry pins or pegs 99 around which, in combination with the jaws 82, the wire or material 9i is wound to provide a polyphase winding. In order to provide such a winding in different lengths, the pegs 9B are not midway of the ends of the arms, and the arms are reversible, having slots. 92 and $3 through which the screws 86 may be passed selectively, according to the length or size of coil desired.

Various changes may be resorted to within the spirit and scope of the invention.
